:have invented a citizen of \lexico,-residing at Santa Rosalia. in the a ne'iv and useful Cushioned ll'heel, of which .the following is aspecification.

Myinrention relates to supporting wheels' for Vehicles of all descriptions including-bi? cycles, automobiles, buggies, hacks, Wagons, '&c., and the Vmain object is to provide an iniproye'd Wheel-'haring internall cushions 'which `serve the purpose of external pneu- `1natic tires which are apt to get punctured,

and ofthe various forms offsprings usually arranged to axles and the lbody vof vehicles.

. proved Wheel may also vserve as a belt tight-- 'driviu'g or driven ener 1n machinery by using it either pulley or -as a roller against oneof the runs of a belt. f

Another' object is to provide a Wheel hav# ing pneumatic tires or other cushions with a supply of compressed air from `i-v'hichfythe,

cushions may be kept fully and quickly in- Hated Without carrying and usinga pump for that purpose.

-A third object is to provide. a Wheel ha. large' pneumatic cushions and smaller cushions which in case the pneumatic ing solid cushions should get injured may b e used until the pneumatic cushions canberepalired or replaced by new ones.

In the accompanying drawing, Figure l is a partly sectionalside eleva-tion of the outer side of my improved Wheel, the right hand half ofthe outer shellof the Wheel'is broken 'away to' expose the inside-parts of the wheel, and of said parts the hub section fourth of the Wheel and the compressed air reservoir is partlyl to left in Fig. 2..

Upon ordinary kin'd that is closed, by the internal .air pressure and opened by a' greater pressure ot air entering through the aperture` In order to easily reach said valved aperture the adjacent shell of the wheel is, provided with corresponding apertures 30, (see Fig. 3) which 'are normally closed by `moved in the left of Fig. 3.) In the annular cavity 32 .of the telly. section are housed one. orniore segnientallycurvedl closed steel .tubes 33' for. carrying highly compressed air;'each of 'said'tubes -orreservoirs has `at one end a reducing chamber 34,' into which the airpasses from the which'automatically reduces the pressure to only the highest pressure desiredin the cushions 26'.` vThe chamber 34 'is provided withv a hose 36 having abend-operated valve 37, and at its reeenjd a coupling 3S adapted to, connect 'with the apertures v2 9 of'the In 2, showntha-t the shell .of the Wheel 'mayI be with one vor morel apertures '39,
